Resolve 10 - LightSpace CMS integration
on Sep 9, 2013 at 3:52:09 pm

Have been testing a bit of Resolve and LightSpace integration here and i find it impressive.

Resolve acts like pattern generator controlled over local network by LightSpace
and feeds your exact image path from computer to monitor
as if you were grading. This gives very precise control over calibration and takes out all the guess work
from signal path.

I also have really radical approach here what i'm playing with.
Resolve V10 beta on mac, Deck Link 4k as video io, Eizo colour series monitor connected to
4k via hdmi. Poor mans setup as i would call it for monitoring if it will work out.

It is just lately that Eizo LightSpace started to play together and DL 4k seemed like good companion
to all of them with Resolve.

What i specially like about this integration part is that i do not have to interrupt
my signal path and just could hook up my probe to LS laptop, connect wifi, and start the profiling.

To me seems really elegant and precise way for calibrating.

I just ordered a hardware bundle from Spectracal that does the same.The Calman5 will generate a 3D LUT for input to the Fujifilm LUT box. From there, I can feed a cheap consumer LCD to get true Rec709(provided that the LCD has a large enough color space. Ive found most Samsung monitors have this.)

Ok. The beauty for me was that Resolve signal path was not interrupted even for calibration.

And monitor has the LUT capability so lut can be loaded directly to it leaving separate LUT box out.

After talking with the folks at Spectracal, it makes no difference whether the correction LUT is applied to the entire monitor or to the application (as in Resolve). The only difference being that I have to remember to disable the node in Resolve that contains my monitor LUT before I generate an output file.

Now i have seen numbers of 99% from rec709 which is pretty good for the price. I'm really exited.

In one of my clients suite there is Penta monitor and it gives me 98 to 99 % and with SDI in of course
but with a lot of different price tag.

I also have to say that about 4000 sample profiling takes about an hour in my setup which in my mind
is mind blowing fast.

Resolve and LS cooperation is fluid and work like a dream.

I have to be specially thankful to Steve from LightSpace to help me out with a million questions
i had in the way to get it working as intended.

This seems to me really accurate poor mans monitoring solution that i piked up from Steves post
in some other forum.

hey Margus

are you using the Eizo's built-in calibration sensor?

Which Lightspace components are you using, so I can price out your setup?

I've never used the Eizo monitors, but I've heard good things.

thanks

Hi.

I did not use internal sensor as it is not accurate that level you would like.

I got one of those:

LS was the Full LightSpace CMS

You can find it here:

http://www.lightillusion.com/place_order.html



And monitor is this one:

Please note that this monitor has only DVI, HDMI and Display port in.

I use it with DeckLink 4K over HDMI.

Looking at the calibration videos for the Calman5, it is entirely realistic to be able to use a LUT on a cheap consumer monitor and get results that are competitive with an FSI or other professional monitor. And by using an inline LUTbox, it's significantly cheaper and more flexible than these built in LUT capabilities in something like the FSI or Eizo. Take a look at the capabilities of the Fujifilm IS-mini, it's an amazing product.

I have both Calman and Lightspace/ Calman's LUT math is far inferior - resulting in far less precision and more banding.

LUT math is like 3D rendering math - each take on it will give you different results.

I would also warn that a cheap monitor will have poor blacks, poor screen uniformity, poor detail in the darks and other issues that cannot be resolved via calibration.

Hi Robert,

did you also already try Calman 5.2 Beta Build build 1324 ?

"Added a new algorithm for interpolating the interior of a 3D LUT. This should help keep the grayscale more consistent and should provide a smoother, more artifact free image."

did not try myself yet but seems promising as far as accuracy / precision / smoothness banding

I tried latest version last week. Yes it's better now, but CMS is still light years ahead.

CALMAN is for home theater calibration and that often shows. Its' really more than good enough for a home theater, but not for us. For one thing, their cube simply does not have enough points. But that makes sense for their market, as it would be impractical for a home calibrator to spend 8 hours waiting for that many slides to go by. He would have to go to his client's house twice, and make sure they disturbed nothing, did not turn on the lights, etc. during his absence At a color facility, we can just lock up, go home, and it's ready the next morning.

The long way CMS uses is still way better.

I found that cms was really fast with my setup.

1d+3d 17 step profiling took just an hour.

That depends on the probe. You may also be using slide times that are too short for good precision. I use 10 seconds with my Hubble.

so it was also 1324 from friday sept 13th you tried?

and would you say that if calman would manage to read more points, and also take more time it could lead to similar as you say "real good" results as cms or do you think there is still problems in the math itself no matter how many points ?
